Offbeat XBOX 360 Game Recommendations for 14 year old?

We just bought older son a X360 for Christmas (250GB, no Kinect, 1 year XLive Gold)

I am a long, long-time PC & Mac gamer, also PSP, DS (GB->GBA before), iPod Touch and iPhone. My genres tend to be FPS and (western) RPG, with turn-based strategy, some RTS, and random others including some jRPG ... and my older son tends to have similar tastes.

Kids already have a Wii and we got younger son a PS2 earlier this year. From those we have loads of casual stuff like LEGO Star Wars and Rock Band/Guitar Hero, a decent set of jRPG through PS2, and a few things like SOCOM2, GTA3, Metal Gear Solid trilogy, etc ...

So far I have 5 X360 games coming (through Goozex): Modern Warfare 2, Fable II, Forza 3, Mass Effect 2, PGR 3. And other stuff requested.

Just was looking for non-obvious recommendations for games - both on the shooter / action side and also more family-friendly stuff.

Thoughts?

Thanks ... I know about some XBLA games like those mentioned above, Trials HD, Defense Grid, 'Splosion, etc ... but want to wait a bit on those. Looking more for boxed up stuff that I can get off of game trading sites to augment the brand new couple of games we got him with the system.

Also, the Orange Box can probably be found very cheap these days. That was a bargain when new and $60, let alone now when it is older and cheap. It's worth it just for Portal, in my opinion.

Yep - already trying to get that. Both kids have played Portal on PC (younger son has played >30 hours of Portal in the last 6 months!) and some HL2, but I know that he'd love to get it on the X360.

Thanks for the Crackdown note - had missed that one!
